Class Reduce2D

Helper class to reduce duplicated or 2d connected curves. To use this class create an empty instance, Add(ICurve2D)/> curves to it and access the Reduced/> property. Some flags add additional control on how the reduction is performed

Syntax

public class Reduce2D : IEqualityComparer<ICurve2D>

Constructors

Reduce2D()

Empty constructor. Use Add(ICurve2D) to add curves.

Declaration

public Reduce2D()

Fields

BreakPolylines

Break up polylines added to this object. Depending on OutputMode the result may again be combined to polylines or paths.

Declaration

public bool BreakPolylines

Field Value

Type	Description
System.Boolean

FlattenPolylines

Precision to remove inner points of polylines. If set to 0, polylines remain unchanged

Declaration

public double FlattenPolylines

Field Value

Type	Description
System.Double

OutputMode

Desired output mode.

Declaration

public Reduce2D.Mode OutputMode

Field Value

Type	Description
Reduce2D.Mode

Precision

Precision: two curves are combined if the resulting curve differs less than this value from the orginal curves.

Declaration

public double Precision

Field Value

Type	Description
System.Double

UsedOriginals

When adding GeoObjects with the method Add(GeoObjectList l, Plane pln), a list of used GeoObjects is maintained when the result "Reduced" is calculated. "UsedOriginals" provides a list of those objects, that are represented in the result. The objects might also be children of the provided objects.

Declaration

public GeoObjectList UsedOriginals

Field Value

Type	Description
GeoObjectList

Properties

Reduced

Access this property for the result of the reduction.

Declaration

public ICurve2D[] Reduced { get; }

Property Value

Type	Description
ICurve2D[]

Methods

Add(ICurve2D)

Adds a curve to the reduction.

Declaration

public void Add(ICurve2D curve)

Parameters

Type	Name	Description
ICurve2D	curve

Add(ICurve2D[])

Adds an array of curves to the reduction

Declaration

public void Add(ICurve2D[] curves)

Parameters

Type	Name	Description
ICurve2D[]	curves

Add(GeoObjectList, Plane)

Add all objects from l, which are or contain curves. The curves are projected onto the provided plane. If l contains composite objects (e.g. Block, Path) the objects are decomposed.

Declaration

public void Add(GeoObjectList l, Plane pln)

Parameters

Type	Name	Description
GeoObjectList	l
Plane	pln
